Ideal for larger whole-house audio systems or commercial/retail spaces, the TSM-12 allows you to connect up to 12 pairs of speakers (12 listening zones) and simplify control with just a push of a button. Equipped with flexible switching options, this powerful and highly efficient dual source speaker selector lets you choose which zones to play via a front panel push-button controls, and the dual source (A/B) switching feature lets you switch between two source amplifiers. Designed for use with either 4- or 8-ohm speakers, connect the TSM-12 to a high current amp and in wall volume controls to create a sophisticated but simplified whole house audio experience.

Equipped with Impedance Protection

To help protect expensive audio equipment, this high-power speaker selector includes low-frequency protection circuitry that reduces subsonic signals so you can safely drive multiple pairs of speakers without going below an amp’s impedance ratings. Going below the impedance rating can overheat or even damage expensive equipment or cause the amplifier to automatically shut off.

Highly efficient, audio-grade impedance-matching autoformers safely distribute maximum power throughout your system, while a rotary switch located on the rear panel can be used to set the appropriate impedance to be seen by your amplifier based on the number of pair of speakers connected.

Designed for Ease of Use

You don’t have to be a technical wizard to install the TSM-12. This speaker distribution system accepts up to 14-gauge speaker wire and includes removable and easily identifiable 4-pole snap-in amplifier and speaker connectors for ease of installation. To simplify control of multiple listening zones even further, we include die-cut labels that can be attached to each button to identify each listening zone, for example, dining room, kitchen, patio, etc.

Specifications

Other Product Info

If you want a powerful speaker selector, the TSM-12 is a highly efficient dual source, impedance-matching speaker selector. It will handle more power and in cooler temperatures than the resister based speaker selectors. This high quality speaker selector is designed for use with either 4 or 8 ohm speakers. The A/B switch located on the front panel allows all your speakers to be driven from either of two amplifiers.

If the AMP is 16 ohm and the speakers are 8 ohm with a total of 12 pairs of speakers what would be the correct setting for the rotary switch. Also, each pair of speakers has a VMS100 set at the default impedance matching setting.
By Customer Service - Q&A on May 4, 2012

Answer:
Hi Michael,

We’ll need to know what amp/receiver you are using that is rated at 16 ohms. Technically, if you have a 16-ohm amp and 12 pairs of 8-ohm speakers, you need a 24x setting. You mentioned VMS100 Volume Controls set to default. It features four settings: 2x, 4x, 8x and 16x. Perhaps bypass the protection of the TSM12 (set it at 1) and set all the volume controls to 16x. Please let us verify the amp information, however, and whether you are connecting a volume control for each of the 12 zones.

By TD from Dayton, OH on March 15, 2012
I have 9 pairs of speakers in my house that all run into a single wire bundle with a lead going to a single 8ohm 100w amp, which keeps shutting off. I put all the impedance jumpers on the room sound controls to x8 and that sort of fixed the amp cutting out most of the time. I have another amp that is a 2x100w, 2ch stereo amp that i want to try, can install this speaker switch using both channels (A & B) from my other AMP to power the spkrs--meaning can i run 5 pair on Ch. A and 4 pair on Ch. B? Or does this switch only allow you to run all 9 pairs on EITHER Ch. A OR Ch. B? Thanks.
By Customer Service - Q&A on March 15, 2012

Answer:
Hi TD:

it would help to know what two amplifiers you actaully have already. Knowing the capabilities of each amplifier/receiver would help determine which would be best for the following. Thinking that one of the amps would work we would recommend purchasing a combination of our DSM6 and DSM4 speaker selectors. You mentioned having Impedance matching volume controls already. I would connect the DSM6 to Speaker A output and drive five pairs of speakers through a volume control for each pair. Then connect the DSM4 to speaker output B and drive the remaining four pairs again using Volume Controls. The first five pair would be set at 8X and the second four pair at 8X to be on the safe side. You can connect your second amplifer/reciever to both DSM as well. This time to the Source B input on each speaker selector. So you would connect Speaker A to Source B of the DSM6 and Speaker output B to Source B of the DSM4. Again depending on your Amplifier capabilities this would give you control over all 9 speakers while adding the capaility of having two sources to pick from for each speaker throughout the whole system.

By Rodman from Philly, PA on March 19, 2012
How big or what kind of amp would I need for this to work well in my store?
By Customer Service - Q&A on March 19, 2012

Answer:
Rodman,
Our Amp300 could drive 12 zones, depending on their power handling of the speakers.

By Jason from Visalia, CA on May 19, 2012
It appears that speaker output from the TSM-12 is only coming from the left side of the pairs. Both left and right had been working. Driving the TSM-12 is a Sony Receiver 7.1 100w x 7. I have only used this three times.
thank you in advance.

By Customer Service - Q&A on May 20, 2012

Answer:
Hi Jason:

We need a little more information. Are you trying to power the TSM12 with a Internal Amplifier (either channel 6 and 7) or an External Amplifier like our AMP300 using the Pre-amplified audio outputs or the Receiver? Can you please try and describe your system in depth? Are you using Volume Controls or depending on the internal protection of the TSM12 to Impedance match the system?

I GET THIS ZONE SELECTOR BUT MY QUESTION IS HOW CONNECTED TO PIONEER RECEIVER VSX-819 H-K?
By Customer Service - Q&A on July 23, 2012

Answer:
Hi Fermin:

There is a Speaker B output on this Pioneer Receiver that will allow you to listen to a separate source. But driving 12 pair of speakers may be a lot to ask for the Room 2 Speaker (B) Level output . If you are looking to add a12 zone speaker selector we recommend adding a AMP200 or AMP300 to connect to the Multi-Room Pre-amp output on this receiver. The Pioneer will handle the source selection as well as control the master volume (from the dedicated remote).

Hi,
My Sony Receiver is connected to my home theater speakers. My TSM-12 is connected to speakers throughout the home and outside on my patio. The Sony Receiver is connected to the TSM-12 through the extra L and R speaker output on the Sony Receiver. When I want to power any of the speakers throughout the home or outside I put the Sony Receiver into a 2 Channel mode which only generates output through the extra L and R speaker output (which is connected to the TSM-12). I select the speakers I want to use on the TSM (which has been just the outside speakers and living room so far). All of the speakers connected to the TSM-12 have separate volume controls in each of the corresponding rooms/areas.
Like I said, this was working great until the last time I used it which was during a party. towards the end of the party it cut out and now only the output from the left side pair of the TSM-12 is working.
Thanks.
jason

Answer:
HI Jason:

Just a couple of questions regarding your system.

What was the protection switch located on the back on the TSM12 set to during this time. Were you using impedance matching volume controls and if so what were they set at? Are they OSD Audio's volume controls? Did you have single pair of speakers per zone? Did you notice if the speaker selector got hot or did your receiver get hot to the touch. Does the speaker selector smell funny like something had been burning? Did you test the outputs of your receiver (attaching a pair of speakers directly to your receiver) to make sure that both channels of the receiver were working? I can give you a better assessment if I know the answers to the above questions.

By Jason from Visalia, CA on May 29, 2012
Re: questions below. The TSM was set to the highest (8-12) for the pairs. The volume controls do not have any jumpers to set and they are not OSD as far as I know (they were there when we bought the house). Each zone has a single pair of speakers. I did not notice if the receiver got hotter than normal and there was no smell. I tested the outputs on the back of the receiver and both work.
Thank you in advance!

Answer:
Hi Jason:

Please contact Brennan at OSD, brennan@osdaudio.com regarding returning the TSM12 so we can check it out. Do you have the ability to remove one of the volume controls and take a picture (send it Brennan) of it so I can confirm the type, Impedance matching or Resistor based. When did you buy the TSM12 and add it to the system?

By pat from canada on May 29, 2012
What type of volume control would work best with this system. I have a harmon kardon receiver avr 300 to hook up to this system. Would this work ok?
By Customer Service - Q&A on May 30, 2012

Answer:
Hi Pat,

It depends if you are using the Harmon Kardon receiver for both home theater and multi-zone for whole house audio or using it to function as a two-channel stereo receiver. In the first example where you are using the receiver for home theater and whole-house, you will need to add an external amplifier like our OSD-AMP200 or AMP300 to connect from the HK AVR and provide the power to the TSM12. If you’re just powering the TSM12 for the whole House with the front speaker output of the receiver, you will not need an additional amplifier. Regarding volume controls, you could use either the SVC300 or VMS300 for inside and the OVC300 for outdoor zones. In all cases where you are using the TSM12 to provide the protection, select the right setting on the back of the unit (depending on the number of speakers connected to the TSM12). The volume controls would be set to 1/2x on the SVC300 and 2x on the VMS300. I hope that helps.

By eric from tacoma wachington on December 15, 2011
can you hook two tsm-12 dual source zones together
By Customer Service - Q&A on December 16, 2011

Answer:
Hi Eric,
We do not recommend you daisy chain these off of a single speaker output. The only exception is if you are using a high current amplifier like our AMP300: http://www.outdoorspeakerdepot.com/stereo-amplifer.html

You would have to connect one TSM12 to Speaker A and the second TSM 12 to Speaker B.
You must make sure you set the protection switch on the rear of the TSM 12 to the proper setting. This will not work using a second zone output from an Audio/Video Receiver or using a cheap 8-ohm power amplifier.

Thank you for considering OSD Audio
